C++ 2023 Week 5

Lesson 10: Integer Types

Integers are whole numbers and the computer can store their exact values... within certain ranges.

John Purcell shows how to use the <limits> constants to find the min and max allowed values of different types of ints, and how to use "sizeof"  to see much RAM they take.

Assignment: There are at least 10 distinct types of integers in C++

Pick at least four types. In your program, declare an instance of each type, assign it a value, output the values.

Conclude the program with a display of the minimum value, maximum value, and "size" for each of your four types type.

Label your output!

 

Lesson 11: Floating Point

Floating point numbers can represent numbers with fractional decimal portions.

Assignment:

Declare at least two types of floating point variable and prompt the user to input values for them.

Use the tools of <iomanip> to display the values in several formats and their "sizeof" values.

Label your output!

 

Lesson 12: Chars and Bools?

TBD

 

[Rodney]

I knew there had to be an option to keep from having to specifically activate what project runs when debugging in a solution, and there is...

Right Click on the solution and open Properties.

There you should see an option to run the selected project versus the default 'Single Startup project' that gets updated each time we select and set a specific project as the startup project.

Change that option (radio button) to 'Current selection' and whatever project is selected in the Solution Explorer at the time of running debug (or release) should run.

@Rodney @Shelton @Roger

Get started early!

I started mine tonight  and found the "limits" and formatting stuff is more fiddly than I remembered it being.

Guys, let's wait on Lesson 12: Chars and Bools.

If you've already done it, great, but we'll catch it the next week if you haven't!
